Elastic moduli of nanostructured carbon films
We have computed the elastic constants of nanostructured carbon films as obtained from classical molecular dynamics simulations of a cluster beam deposition process. The calculations show that the elastic constants of the deposited films are related to the average size of the clusters by a power law. This allows us to extrapolate the present theoretical data to the scale of the experimental res...
متن کاملMolecular Dynamics Investigation of The Elastic Constants and Moduli of Single Walled Carbon Nanotubes
Determination of the mechanical properties of carbon nanotubes is an essential step in their applications from macroscopic composites to nano-electro-mechanical systems. In this paper we report the results of a series of molecular dynamics simulations carried out to predict the elastic constants, i.e. the elements of the stiffness tensor, and the elastic moduli, namely the Young’s and shear mod...
متن کاملBenzyne cycloaddition onto carbon nanohorns.
A facile approach for the covalent functionalization of carbon nanohorns (CNHs) based on the benzyne cycloaddition reaction is presented. The benzynes were in situ generated from either anthranilic acid by decomposition of the internal benzenediazonium-2-carboxylate or from 2-(trimethylsilyl)-phenyl triflate by fluoride ion attack at the silicon atom followed by displacement of the trimethylsil...
متن کاملReductive dismantling and functionalization of carbon nanohorns.
Reduction of carbon nanohorn (CNH) aggregates with potassium naphthalenide resulted in their dismantling and individualization. Furthermore, the reduced CNHs were functionalized via addition of electrophiles.
متن کاملElectronic and structural properties of carbon nanohorns
We use a parametrized linear combination of atomic orbitals calculations to determine the stability, optimum geometry, and electronic properties of nanometer-sized capped graphitic cones, called ‘‘nanohorns.’’ Different nanohorn morphologies are considered, which differ in the relative location of the five terminating pentagons. Simulated scanning tunneling microscopy images of the various stru...
